How to Configure Binatone airtel modem for BSNL!

Started the painful friendship with BSNL.... Got BSNL landline after waiting for 18 days. Now am unable to configure my Binatone modem (54M ADSL2+). Tried at BSNL exchange itself by a so called BSNL expert.

I have tried these settings. but no internet.
Is there a possibility that given username or password is not activated????
Or is there any other settings which I need to change. (like Gateway IP... )
Please help........

Did you check the MSS/ MTU value ? change to 1492 or even lower in steps of 8.
It is better to say I used Beetel 220BXI or Beetel 450BXI unit for connecting to BSNL broadband.
(similar to WA3002_g4/ DNA A212 etc )and could connect to internet.

Now Binatone DTW 845W (?)wifi router is almost similar to WA3002_g1/Beetel450TCI/ SAM 300AX etc) with minor variations .
( Firmware has been modified by Airtel for wifi with default ssid key )

Ok. let me check up again the data
..... Confirm Post No 9.
....... MTU to default 0
A)
If you are on PPPOE mode , switch to 1483 bridging and try.

(B)
May be a firmware upgrade or downgrade required.
(C)
can you try the modem/router in a friend's system ?
(D)
or a wild try:
try PVC0. with Bsnl vpi/vci 0 and 35.
(First change in PVC2 random data say 1 and 37)
All PVC's will show same snr/attn etc . except WAN details.
and in the end adsl status. CONNECTED.
One user has reported success with this. NO LOGIC !!

@tiger4132
You can make screenshots of ALL the modem/router pages "as it is"
now to find out WHY you cannot connect to BSNL Broadband still.
Post as annexures. May be some other member can find the reason.

REP++24points from me pending.

Para two:

Since I am not using Wifi for current testing using Binatone, will wifi settings create a problem?
I thought of configuring wifi, once wired line is cleared.

sorry:
I did not know that unless lan connection is set you should not even look at wifi page!! You were not asked to make settings there Post no 20.

Congrats:
If you want: if another ssid is available you can create your own.
Do not attempt to change the present Airtel SSID.
Check other wifi links appearing in your laptop.
( for similar name )
Check for unusual downloads in your connection.
Then this SSID has to be blocked.
Remote possibility, some one knows and uses the same security key in your locality!
I cannot acccess your wifi network!!

Solution. Downgraded my firmware version to DT4W-A1.002
(it was DT4W-4.007)

I upgraded it first to DT4W-5.00, which I got from airtel site. But didnt work. Later I downgraded to the said version.

I will post the screen shots of all options later on.

Thanks everyone for the help. thanks essbebe

Thank you so much for posting this reply here. I was just about ready to throw the Binatone Router out the window. This was a huge help and it worked.

Only funny thing is it seems to go back to its previous behaviour once I turn it off and on again. So I've updated the firmware a bunch of times even though it still shows as V1.002. So I have basically left it on all the time and not shut it down in a while.

Deactivate ACL and cwmp options.
Deactivate all PVC's except PVC2 for BSNL vpi/vci 0 and 35
Reboot from current settings.
Wait for the slide to show re booting.
Try again.
feedback.
( I am using similar model 110TCI less wifi diffferent FW)

I deactivated all PVC except PVC2. Internet is working fine in Bridge mode using the dialer method in Windows. I plan to use it for a laptop and I think it has to be changed to PPPoE mode to use the wireless. Laptop connects to the network but there is no internet connectivity. PVC2 status shows as PPP Password Invalid. Attached a screenshot of the PVCs summary

Some day b4 my Bintatone modem was comfortable with BSNL broadband. bt after upgradation of firmware for Model No. DT 845W ver1.0 Wireless ADSL2+Router to ver5.008, it stopped working connecting BSNL and i changed some settings many times, bt it shoked me that after on/off the modem many times, it always comes to its default settings to ver5.008. I tried to search many times in google but in vain and also tried to downgrade the firmware to 2.0 but failed. i cudn't find the previous ver of firware v1.0. at last i found the indiabroadband form as helping community to each other. Suggestions welcomed.

my problem is different .. i too have the same binatone modem provided by airtel.A.005
the internet is working fine but in bridged mode pvc0 vpi/vci 0/35, pvc2 0/32 pvc1 1/32 all the three active. my problem is that i am not able to connect my another laptop or mobile with this network. i tried ppoe mode for pvc0 and deactivated pvc1 nd pvc2. the status shows connected ppp up ping the yahoo, but i m not able to browse internet. IS DOWNGRADING THE ONLY OPTION AVAILABLE?
